No sign of whale in morning fog

A gray whale that wandered into San Diego Bay last week was believed to still be cruising the harbor’s waters Wednesday, though it was hard to spot in the morning fog.

The 30-foot cetacean, which was first spotted March 10 offshore from Shelter Island, was spotted swimming around the Coronado Bridge Tuesday, according to the U.S. Coast Guard.

As of Wednesday morning, no sightings of the whale had been reported to the agency but authorities believe that was due to some heavy fog, Coast Guard Petty Officer Henry Dunphy said.

Federal officials have urged boaters to stay at least 100 yards from the mottled-slate-and-white-colored mammal.

On Monday, the Coast Guard announced it was suspending its monitoring of the whale’s movements pending any further requests from the National Marine Fisheries Service.

Wildlife officials hope the whale will soon find its way back into the ocean to join fellow grays on their annual migration from the lagoons of Baja California, where they calf and mate in wintertime, to Alaskan waters, where they summer.
